उत्तर
All of these.
Explanation:
The solar energy that reaches the Earth is composed of a mix of infrared waves (long waves), ultraviolet rays (short waves), and PAR (Photosynthetically Active Radiation − visible spectrum). The approximate proportions are about 49.4% infrared rays, 42.3% PAR, and 8% ultraviolet rays. Together, these form the solar energy received by the Earth’s surface as incoming solar radiation or insolation.
